AUGUSTUS F. TRIPP AND IGNATZ WOEPPEL, OF BUFFALO, NEw YoEK, As:

SIGNOBS TO SIDNEY SHEPARD 8t (30., OF SAME PLACE.

FLOUR-SIFTER.

SPECIFICATION forming part of Letters Patent No. 322,141, dated July14-, 1885.

' Application filed October 29, 1884. (N 0 model.)

To all whom it may concern:

Be it known that we, AUGUSTUS F. TRIPP and IGNATZWOEPPEL, both of thecity of in the county of Erie and State of New York, have invented newand useful Improvements in Flour-Sifters, of which the following is aspecification.

This invention relates more particularly to an improvement in that classof metallic sieves which are employed for sifting flour; and it has forits object to produce a strong, light, and durable sieve atcomparatively small expense.

Our invention consists,to that end,of the improvements hereinafterdescribed,and pointed out in the claim.

In the accompanying drawings, Figure l is a sectional elevation of aflour-sieve provided with our improvements. Fig. 2 is a top plan view,and Fig. 3 a perspective view, same. Figs. 4 and 5 are vertical sectionson an enlarged scale, illustrating the manner, in which the wire-gauzebottom is secured in lace.

Like letters of reference refer to like parts in the several figures.

A represents the cylindrical shell or body of the sieve; B, the handlesecured thereto; 0, the wire-gauze bottom, and D the stirrer, arrangedto rotate upon the latter.

The wire-gauze bottom G is secured on the lower portion of the body A inthe following manner: 6 represents an inwardly-projecting bead formed inthe lower portion of the body A, to serve:as a shoulder, whereby thebottom 0 is held against upward movement. The edge of the bottom 0 isturned downward to form a flange, f, and placed against the inner sideof the bodyAbelow the bead e.

G is a ring placed against the inner side of the flange f of the bottom,and provided with an inwardly-projecting top flange, g, and anoutwardly-projecting bottom flange, g. The latter extends outwardlybeyond the lower edge of the body A. When the bottom 0 and ring G havebeen placed in the body A in this manner, which is represented in Fig.4, a bead, h, is turned outward in the upper corner of the ring G,through the latter, the bottom 0, and the body A, whereby the bottom isfirmly clamped between the ring G and the body A, and at the same timestretched. The lower flange, g, of the ring G is turned upward againstthe outer side of of the turned flange, f, a ring,

the body A, whereby the ring G is secured to the body A. These partshave now assumed the form represented in Fig. 5, and the bottom isthereby secured to the body in a very simple and reliable manner.

The stirrer D is composed of two horizontal arms, 11 4., arranged nearthe upper surface of the wire-gauze bottom 0, a stem or spindle, j, anda hand-crank, is. All of these parts are bent to the desired form, asclearly repre sented in Fig. 1. The wire extends from the lower end ofthe spindle j outwardly almost constructed of a single piece of wire tothe inner side of the body A; then across the bottom almost to theopposite side of the body; then back to the center, where it terminatesin a journal or step, Z, which is supported in a bearing secured to thecenter of the wire-gauze bottom.

The handle B is provided along its edges with two stiffening wires, 4n.These wires extend from the upper end of the handle inwardly to thecenter of the body A, where they are coiled to form a bearing orsupport, a, for the spindle j of the stirrer. The two wires m' mand'coil n are constructed of a single length of wire construction issecured.

It will be understood that while we have shown and described a completeand operative sifter, we make no claim to any features of itsconstruction other than those set forth in the following claim.

We claim as our invention.-

The combination, with the body A, provided with an inwardly-projectingbead, e, of the bottom 0, provided with a downwardlythe inner side ofsaid flange, and provided with a top flange, g, and a bottom flange, g,the parts being secured together by ahead, it, formed through the ringG, flange f, and body A in the upper portion of the ring G, and by thelower flange, being turned up against the outer side of the body A,substantially as G, placed against bent to the proper form, as shown,whereby a strong, light, and cheap set forth. 7 Witness our hands this20th day of October, 1884.
